FIELD OF THE INVENTION

The present invention relates generally to the use of database query results, and more specifically, to systems and methods for changing contents of a query result set displayed according to a graphical representation.

BACKGROUND

Data retrieval tools are widely available for querying a database and displaying the query results in a grid or table to a computer user. The grid or table is generally organized into rows and columns. Query result values can be displayed at data fields arranged as cells formed by the rows and columns. A user can define selection criteria and/or customize the query results by column sorting, filtering based on field values, and the like, in order for the query results to be displayed at a useful manner to the user.

Data visualization techniques can be applied when a user selects one or more rows of a database table, whereby the selected items can be displayed as a histogram, bar graph, and the like. Once the graph is displayed according to a conventional approach, the underlying contents cannot be changed.

DETAILED DESCRIPTION

In the following description, specific details are set forth although it should be appreciated by one of ordinary skill that the systems and methods can be practiced without at least some of the details. In some instances, known features or processes are not described in detail so as not to obscure the present invention.

The embodiments described herein provide for a presentation of data that allows users to make straightforward and natural changes to query result records without relying on conventional hard-to-discover context menu options, query modifications, or separate dialogs. The embodiments overcome limitations regarding conventional approaches for temporarily viewing different visual representations of a query result set for the purpose of making edits to its contents. One such approach is for a user to view a form in a display window that represents a single detailed record corresponding to a result row of a database table. Another approach is for a user to modify query criteria to change the display of the query results, or perform column sorting or related adjustments, for example, to rearrange a tabular representation of the data.

The embodiments referred to herein also overcome limitations regarding conventional approaches when users desire to make multiple changes to the query results quickly or to perform an action on multiple records at once. One approach is for a user to select multiple rows of a query results table, and modify the selection by using a context menu to invoke a batch update. For example, a drag-and-drop operation can be performed where the selected records are moved to a dialog box configured with a field value, whereby the selected records can each be changed to that field value. However, batch updates are generally made without a clear understanding of the relationship of the selected items with respect to the other elements of the result set. The batch update operation is also oriented to a subset of data in the result set, for example, a single field value common to a handful of records. Batch update dialog boxes and/or context menu options often display field values for certain records but do not display other records in the result set that share those values.

Another conventional approach is that users can select multiple records of a result set at the same time, and rearrange the result set accordingly by column sorting or modifying an existing query to allow for an easier selection of the rows that they want to change. When changes are made to the result set in this manner, problems can arise if the modified rows are re-inserted in sorted order they will disappear from view and that by leaving the modified rows in place is an indication of the result set no longer properly being sorted.

In brief overview, the present inventive concepts include systems and methods for visually presenting a query result set in accordance with one or more different graphical representations on a display, and permitting a user to modify underlying field values of the query result set when navigating between different the representations. During an operation, a user can run a database query. A field graph or other graphical representation of the query results can be displayed. The records of the query results can be positioned about vertices, also referred to as nodes, and organized according to the contents of the query result set. For example, one or more records of the query result set can be positioned about a particular vertex when a field value of the record is the same as a value corresponding to the vertex. The displayed field graph can also include directed edges, or arcs, extending between the vertices to indicate possible transition paths for the records.

A field value of one or more records can be changed by moving a record positioned about a first vertex to a second vertex representing a different field value. For example, a user can perform a drag-and-drop operation to transition the selected record from the first vertex to the second vertex, or by highlighting an arc extending between the first vertex and the second vertex. In this manner, an original field value can be removed from a record when the record is moved from the first vertex to a different vertex, referred to as a second vertex. Accordingly, the record is changed to include the field value corresponding to the second vertex. A consistent view of the graphical representation of the query results can therefore be maintained regardless of changes made to the records.

A user can also change between different visual representations to obtain different views of the query results. For example, a user can select a different field type from a tab on a graphical user interface (GUI), thereby displaying a different field graph for the same query results. Here, the user can change one or more field values under the newly selected field type by performing a drag-and-drop operation or highlighting an arc in a similar manner as described above.

In another embodiment, at least one freeform vertex is provided that displays a dialog box, pop-up, and the like for entering new field values, or presenting one or more other field values of the query result set. Query result records can be modified to include the new field values by positioning the records in a region proximal to the freeform vertex, or by highlighting an arc extending between the record and the freeform vertex, or by other approaches described herein.

Also, multiple field types can be simultaneously selected and represented by forming a product of field values under the field types. For example, multiple columns of a database table, each corresponding to a field type, can be selected, whereby a field graph can include vertices that each can display multiple field values, instead of a single field value. If a record has field values that match the field values identified with the vertex, then the record is positioned in a region proximal to that vertex. The record can be transitioned to another vertex having multiple fields, whereby the record is updated with the fields of the other vertex, similar to that described herein with respect to other embodiments.

FIG. 1 is a block diagram of a computer system 100 in which embodiments of the present inventive concepts can be implemented. The computer system 100 can be a personal computer, server, smartphone, or any other electronic device known to those of ordinary skill in the art.

The computer system 100 includes at least one processor 102, for example, a CPU, a memory 104, and a display 108. The memory 104 can be volatile, for example, RAM, or non-volatile, for example, ROM, flash memory, and the like, or a combination thereof. The memory 104 can include removable and/or non-removable storage media implemented in accordance with methods and technologies known to those of ordinary skill in the art for storing data. Stored in the memory 104 can include program code, such as program code corresponding to an operating system, graphical user interface, and systems and methods in accordance with the present inventive concepts described herein.

The computer system 100 can include a user interface in communication with one or more I/O devices 106, such as a keyboard, a mouse, a trackball, and/or a touchscreen. An I/O device 106 can include an interface for communicating with a display 108, which can present one or more visual representations of query result data to a user in accordance with the present inventive concepts. The computer system 100 can also include a network interface 110 that allows the computer system 100 to communicate with other devices via a network (not shown) such as a WAN, a LAN, the Internet, and the like, or a direct connection. The computer system 100 can include additional hardware and/or software components known to those of ordinary skill in the art, for example, one or more connectors such as a USB connector for coupling to other electronic devices such as a flash memory stick.

The processor 102, memory 104, the I/O device 106, the display 108, and the network interface 110 can communicate with each other over one or more communications busses known to those of ordinary skill in the art, for example, a Peripheral Component Interconnect (PCI) bus.

FIG. 2 is a block diagram of a query result management system 200, in accordance with an embodiment. The query result management system 200 can execute on a computer system, for example, the computer system 100 described in FIG. 1. The query result management system 200 can be configured to operate with a graphical user interface. Elements of the query result management system 200 can be installed in different memory devices of one or more computer systems. Elements of the query result management system 200 can be executed by different processors on the same computer system or on different computer systems. Elements of the query result management system 200 can communicate with each other via one or more communications busses, network connectors, and/or intervening communication devices known to those of ordinary skill in the art.

The query result management system 200 can include a database query engine 202, a graph generator 204, a data field adjustment module 208, and a pop-up generator 214.

The database query engine 202 communicates with a database 210. The database 210 can be integrated with, and/or part of, the query result management system 200, for example, sharing the memory 104 with the query result management system 200. Alternatively, the database 210 can be separate from the query result management system 200, and in communication with the query result management system 200 via a network or other direct or indirect connection. The database 210 can include a data repository known to those of ordinary skill in the art, for example, a relational database. The database 210 can include one or more well-known repositories for storing user data, schemas containing metadata, and the like.

The database query engine 202 can perform a query of the database 210 to export data from the database 210 based on a set of user-defined search criteria. The database query engine 202 can communicate with a database browser, editor, wizard, export tool, and the like, to perform a query, which can include specifying filter criteria, fields, and other selection criteria related to the query, and/or view query results in a data base file, for example, a table. The database query engine 202 permits a user to interact with the result set, for example, via a display editor.

The graph generator 204 outputs the query results to a display, for example, a computer monitor or a touchscreen, as a graphical representation. In an embodiment, the graphical representation includes a field graph or other graph image that includes vertices and arcs extending between the vertices.

The graph generator 204 includes a vertices arrangement unit 206 that can display the records in the result set around a region proximal to the vertices of the generated graph, for example, as graphical icons. The graph generator 204 can arrange the vertices in a display area provided by the display 108, and correct or modify the positioning of the individual vertices in the arrangement when vertices are added or removed, for example, when record field values are added, removed, or changed, whereby corresponding vertices can likewise be added, removed, or changed. When the graphical representation changes, for example, by selecting a different field type, the graph generator 204 can produce a different graphical representation. The graph generator 204 can also display field values that correspond to the vertices. The graph generator 204 can display one or more records having a common field value in a region proximal to a vertex displaying the same field value. For example, as shown in FIG. 6, a vertex entitled “Resolved,” can have a display window that includes a listing of records, e.g., SAMPL00000003, etc. having a Resolved field value.

The graph generator 204 includes an arc arrangement unit 212 that can generate one or more arcs that extend between vertices. An arc represents a possible transition between two vertices. The positioning of the arcs can be determined from relationships between record field values of a given field types. A different graphical representation of the same result set can be displayed, for example, by selecting a different field type. Here, the arc arrangement unit 212 can change the positioning of the arcs between vertices of the newly selected graphical representation. A record positioned at a vertex includes a field value corresponding to the vertex. Thus, when an arc is selected, for example, the record can be moved to a different vertex having a different field value. In an embodiment, a selected record at one end of the arc is changed to include the field value identified at the vertex at the other end of the arc. In another embodiment, a selected record proximal to a first vertex at one end of the arc is dragged and dropped into a dialog box, pop-up, and the like that is displayed at a region proximal to the second vertex at the other end of the arc, whereby the selected record is changed to include the field value identified at the second vertex.

Each record includes a set of possible transition paths. A selection of a record can therefore result in the set of possible transition paths being displayed as arcs, and transition paths being formed via the displayed arcs to destination vertices at the other end of the displayed arcs. When a user selects a record at a vertex, arcs are drawn or highlighted that represent the possible transition paths from the vertex to other vertices allowed on the graphical representation. For example, referring to FIG. 6, when a record identified as “SAMPL00000012” is selected, arcs can be displayed that show possible transition paths to vertices identified by “Resolved” and “Open” field values, respectively. In an embodiment, multiple records can be selected whereby an intersection of all sets for the selected records can be computed, and only those transition paths corresponding to the selected records are displayed. For example, if three records are selected, and possible transitions are displayed for only those three records. In another embodiment, the transition paths of all records, not just the selected records, can be displayed.

The data field adjustment module 208 can change a field value of a record to be populated with a field value identified at a vertex when the record is moved on a display to the vertex. The updated record can be displayed at a field graph or other graphical representation. For example, if a user selects that a database table be displayed instead of a field graph, the updated record can be displayed at the table having the newly added field value.

The pop-up generator 214 produces a dialog box, pop-up window, and the like, whereby a user can modify a result set by entering a new record field value. The pop-up window and the like can be located at a vertex. The new field value can be displayed at the vertex. A user can transition a record to the vertex, for example, a window for displaying records having the new field value, whereby the record is updated with the new field value. The arc arrangement unit 212 can display arcs that show possible transition paths from other vertices to the vertex having the new record field value.

FIG. 3 is a flow diagram of a method 300 for using a graphical representation of a query result set to modify query data, in accordance with an embodiment. Some or all of the method 300 can be performed on an electronic device comprising at least a processor and memory, such as the computer system 100 described with reference to FIG. 1. The method 300 can make use of the query result management system 200 and/or a graphical user interface, a database query application, and/or other well-known computer applications.

According to the illustrated embodiment, a query is performed 310 to export or otherwise retrieve a result set from one or more storage repositories such as the database 210 shown in FIG. 2 according to user-defined selection criteria. The result set can be organized into a table or other well-known format, and can include data, for example, meta-information about column names or other query-related information. Each row of the result set can correspond to a database record, also referred to as a query result record. Each column of the result set can correspond to a record field type. The query result set can be displayed as a table or other well-known format on a computer display.

A field graph or other graphical representation can be generated 320 from the query result data. The graphical representation can be displayed by selecting a record field type from a result column, a field picker interface, or other user interface that displays a set of fields for selection by a user. The field graph includes a plurality of vertices. Each vertex can have at least one corresponding field value of the result set. The records collected from the query are visually presented at the vertices, according to a match between field values of the records and the field values corresponding to the vertices. The records can be arranged about the vertices of a field graph according to the field values. The records can be listed in the display window, dialog box, pop-up window, and the like at a corresponding vertex. The records can be added to or removed from the display window, dialog box, pop-up window, and the like by a mouse, keyboard, or other computer input device.

The field graph can also include a plurality of arcs that extend from the vertices to illustrate possible transition paths between records positioned in regions proximal to the vertices. The arcs can be displayed when the graphical representation is formed, or the arcs can be presented upon selection of a record having a field value to be changed.

One or more records can be selected 330 from the query result data. As described above, a field value can be displayed at a vertex of the field graph indicating that each record at the vertex includes the field value. One or more query result records at the vertex can be selected, for example, using a computer input device such as a mouse or keyboard. In an embodiment, arcs are displayed showing possible paths between records in the result set, and the records are shown as icons about vertices. For example, when the record is selected, the relevant arcs can be highlighted to show the possible paths to other vertices where the selected record can be transitioned.

A field value of the selected query result record can be changed 340 to a different field value by transitioning the selected query result record to a different vertex of the graphical representation. The user can determine a transition path for the selected record by selecting an arc extending from the selected record to the destination vertex. When the arc is selected, the record can be moved to a display box in a region proximal to the destination vertex. In another embodiment, the selected record is dragged and dropped into the region proximal to the destination vertex.

FIG. 4 is a flow diagram of a method 400 for using a graphical representation of a query result set to modify query data, in accordance with another embodiment. Some or all of the method 400 can be performed on an electronic device comprising at least a processor and memory, such as the computer system 100 described with reference to FIG. 1. The method 400 can make use of the query result management system 200, and/or a graphical user interface, a database query application, and/or other well-known computer applications.

According to the illustrated embodiment, a query result set is received 410, for example, by exporting a result set in response to a query from one or more storage repositories such as the database 210 shown in FIG. 2. A query can be performed to retrieve the query result set in a manner similar to that described in step 310 above, and will therefore not be repeated for reasons related to brevity.

A field graph or other graphical representation of the data identified from the query result set is generated 420 and displayed on a computer monitor, touchscreen, or other display known to those of ordinary skill in the art. The field graph includes a plurality of vertices. A different field value of the result set can correspond to each vertex. The field graph can be changed to a different graphical representation, for example, by selecting a different record field type at a graphical user interface, which can include different field values than those displayed at the previous graphical representation. Accordingly, the new graphical representation can include different vertices and/or arcs, and can be displayed with different record field values under the different record field type.

The query result records from the query result data can be arranged 430 about the vertices of the field graph. Each vertex can include a display window and the like that identifies a field value. A list of records can be displayed about the vertex, each of which includes the displayed field value.

The field graph can include at least one freeform vertex 440. A dialog box, pop-up form, blank field, and the like can be displayed at a region proximal to the freeform vertex for the user to enter 450 a field value. The field value can be a new field value that is added to the query result set. A new field value can be entered by typing it into the dialog box, or dragging the new field value from a list, table, and the like, and dropping it into a dialog box in a region proximal to the destination vertex. The freeform vertex 440 can be used as a catch-all or “other” category for displaying other record field values under a field type where there are too many field values to display. Transition arcs can extend to the freeform vertex from other vertices in the field graph. At least one record can be selected 460. The selected record can be transferred to the dialog box of the freeform vertex having the new field value by highlighting the arc between the source and destination vertices, or by a drag-and-drop operation, i.e. using an input device such as a mouse to drag the selected record from its original vertex into the freeform vertex. Accordingly, the record can be modified 470 to include the new field value displayed at the destination vertex.

FIG. 5 is a screenshot of a query result set displayed at a database file 500, in accordance with an embodiment. The database file 500 can be displayed at one or more different formats by the query result management system 200 using a data visualization program such as a spreadsheet application, workflow automation application, change management application, and the like, for example, IBM® Rational® ClearQuest®. One format can include a table organized into rows and columns. Each row can correspond to a record, for example, record 502. Each column can correspond to a record field type, for example, a field type 504 entitled “State.” Each record includes a plurality of fields, which can be populated with field values. For example, record 502 includes a field value 506 “Submitted” under the field type 504 entitled “State.” The field values can be available for graphing, for example, presented in a field graph shown in FIG. 6. A user can select one or more rows and/or columns of the database file 500, and submit a request to generate a field graph from the contents of the selected contents to the query result management system 200, or a data visualization program in communication with the query result management system 200.

FIG. 6 shows the query results of FIG. 5 arranged in a field graph 600, in accordance with embodiment. The field graph 600 can be displayed using a data visualization program in communication with a graphical user interface, for example, an IBM® Rational® ClearQuest® application. The field graph 600 can be generated according to a field type selected by a user. For example, when the field type 504 entitled “State” is selected, the field graph 600 can display a status of a software bug (i.e., Submitted, Resolved, etc.). The state field values, i.e., Submitted, Resolved, etc., can be determined from a result column of a query result set. Accordingly, the field graph 600 can be displayed at a similar manner as a state diagram. For example, transition arrows 604 extend between vertices 602, 606 to indicate a possible transition between states, i.e. vertices, for a record located at the vertex 602. Each vertex corresponds to a record field value. Thus, the location of a record is determined by a match between a state field value of the record and the state identified at the vertex.

In one example, the Submitted record field value 506 is positioned at a vertex 602 of the field graph 600. In another example, the Open record field value 608 is positioned at a vertex 606. The record field values can be displayed at a window or box, for example, display window 610, proximal to the vertices. A listing of records having the field values can be listed in the window or box, for example, record 502.

When a record 502 entitled “SAMPL00000011” of the query results is selected, transition arrows 604 can be generated that indicate possible transitions to vertices having state field values Open and Resolved, respectively.

A user can change the state field value of the record 502 by selecting a highlighted arrow 604 or dragging the selected record 502 to the vertex 606. Accordingly, the state field value of the record 502 can be changed from “Submitted” to “Open,” as shown in the field graph 700 of FIG. 7.

FIG. 8 shows the query results of FIG. 5 arranged in a field graph 800, in accordance with another embodiment. The field graph 800 can be displayed using a data visualization program, for example, described herein.

Here, a different graphical representation of the query results of FIG. 5 is shown than the graphical representations of FIGS. 6 and 7. Namely, a field type 804 entitled “Priority” is selected instead of the field type 504 entitled “State” of the field graphs 600, 700 shown in FIGS. 6 and 7, respectively. By selecting different field types in this manner, users can easily switch between different representations of the same query results. Each graphical representation can display different field values, depending on the selected field type. For example, in FIG. 8, record 502 of the query results is shown having a record field value 806, i.e., “None”, under the Priority field type.

FIG. 9 shows the query results of FIG. 5 arranged in a field graph 900, in accordance with another embodiment. The field graph 900 can be displayed at accordance with the method 400 described herein with reference to FIG. 4. The field graph 900 can be displayed using a data visualization program, for example, described herein.

The field graph 900 can include a pop-up window, dialog box, blank field, and the like for entering new field values. For example, a value 904 called “Enhancements” can be added to the “Other” dialog box 902, which is used as a catch-all field for entering new field values. Alternatively, the freeform vertex 440 can be used for displaying a list of records having field values that are not assigned to a vertex, for example, where there are too many field values under the displayed field type. Transition arcs 906 can extend to the freeform vertex from other vertices. For example, an arc 906 can extend from the dialog box 908 include a “None” field value. Records can be selected from the None dialog box 908, for example, record 910, and transferred to the dialog box 902 by selecting the arc 906 or a drag-and-drop operation. The Enhancements value 904 can be added under the Priority field type 804. The title of the dialog box 908 can be changed from “Other” to “Enhancements.” A new “Other” dialog box can be generated at the field graph 900 to replace the dialog box 902 reconfigured for the Enhancements value, for example, by a user-selectable option in the user interface.

FIG. 10 is an illustration of the query results of FIG. 5 arranged in another field graph, in accordance with an embodiment. In an embodiment, multiple field types are selected, which can correspond to multiple columns of the database file 500. For example, the Priority field type 1004 and the State field type 1006 can both be selected. A field graph can be generated that represents the field values of each field type by forming a product of the field values. For example, vertices can be generated that display “Resolved/Normal,” 1008 “Open/High Attention,” 1010, etc. The maximum number of displayed vertices can be predefined. A user can select combinations of certain field values to be displayed about vertices. The field graph can be configured such that a number of field values and/or a number of vertices do not exceed a predetermined number. A separate vertex can also be displayed, which includes the remaining field value combinations, for example, less relevant combinations. This vertex can be identified by a generic term such as “Others,” instead of identifying the remaining field value combinations.
